Y., ASSIGNORS TO 'WATER- PROOF POCKET CORPORATION, A CORPORATION OF NEW YORK SAFETY GONTAENER Application filed February 1,1, 1928. Serial No. 253,542.

The invention herein relates to ire and water proof packages and in order toexemplify it in its most potent form, it is illustrated in connectionwith a mail bag.

Mail bags, as used -for transporting valuable mailsfrom point to point, are ordinarily made of canvas or duck fabrics, reenforced and sewed and provided with a closure of some sort which can be sealed to form a lock. Usually, the neck of the mail sack is secured by a cord or Vthe like, and in some instances, these cords are provided with locking arrangements to insure transfer without access to thecontents of the bag.

3 The developmentof theairplane has led to the necessity of providing a more secure means of transferring mails and valuables. It is therefore the object and intention of the present invention to produce a receptacle along the lines of mail bags and conforming to their general specifications, but with the added features of being fireproof, waterproof and more essentially buoyant. l

The accomplishment of hese features is 'l' hereinafter more fully described.

`Referringto the drawings: i i Figure l, is a perspective view of such a `mail `bag hanging on a mail rack with closure open. i

Figure 2, is a partial sectional view illustrating the arrangement of the various fabrics and the closure. Y y

Figure 3, isavertical crosssectional view through the closure, clamp and pertinent arts. y While the device'is desirable in `ordinary mail transportation, it is especially adaptable and useful for the air mail service.

Not infrequently, air planes are subject to `immediate descent where thevaluable load carried may be subject to immersion and loss `in streams or lakes;

Furthermore, not infrequently, in such service, fire from the gasolene tanks occurs.

"The pouches are, of course, contaminated with the inflammable materials and the contents of the mail bags are burned, often at great loss and inconvenience.

It is therefore, the principalobject of the present invention to provide a container,

which whether used as a mail bag orotherwise, `will have characteristics of resisting lire and consequent destruction and will also have a buoyancy which will `float them for an almost `indeiiniteperiod in case they are dropped `in lakes, rivers or the sea.

In carrying out the invention, we provide a bag made up of several individual bag structures which are all cemented together and attached to a closure frame, which frame may be locked against access and serves through its locking apparatus as a clamp` for securing the frame and the bags positively against ingress of moisture. y

In the accompanying drawings, referring particularly to Figure l, there is a hinged closure l, to which the bag 2, is secured.

This closure consists of two frame members 3, 4l, pivoted as at 5. The frame member 3, has a lip piece 6, which serves as a rest and stop support for the cooperating member 4. This permits hanging the bag through the hand loop 7, of the clamp 8, to the rail 9, and hook 10, of a distributing frame.

The clamp 8, is hinged as at 11, and the frame member 3, has a staple l2, passing through the body of the clamp member 8. This staple 12, forms a convenient means of applying a lock 13 which securely holds the clamp in position. The clamp extends on both sides of the frame parts 3, 4, and securely locks them together and holds them.

The bag structure which is applied to the frame members 3, 4:, consists preferably of a series of fabrics.

rIhe outer fabric A, may be of canvas or duck k'which has been treated to a lireproof and waterproof solution and within this again volume bf air is left between the bags C, and

D, which is suiiicient to give complete buoyancy to the entire structure when under full load.

Naturally, there is a certain amount of air between the two canvas bags A, and B, which aids in giving buoyancy, but in the event of the bags A, and B, being destroyed for any reason such as fire, rips or tears, the inner bags C, D, will in conjunction with the air space within the bag and its contents provide sufficient buoyancy to keep the whole device with its contents afloat In making up the structure, the principal bags A, B, of fire and Waterproof duck orY canvas and the thinner inner bags D, C, of rubberized fabric or full rubber structure are vulcanized together, adjacent to the neck of the bag and to the upper end of the bag where it is attached to the frame parts 3, 4.

i This vulcanization insures a `complete homogeneous structure off thewariousbag elementsfnotonlyfwhere 'they are oin'ed and connectedl withLY the'L framefpa'rts, but" forf'a slight"distance',` beloWthe iframe'.` I

'This 'serves' as 'a continuous" member "over the hinge "p'oi'nts ofthe frame"membersv` and serves `asa complete closure. j l `The continuous f` strip i y18, `while havin a spongy,l interior,v has fa-closed rubber fsurtace on bothsidesand edges and *thusl gives a full cushioning effect? Awhich "will permit= ofthe closet compaction when underpressure of4 the l. l im@ Y .4. y It twill bequite' obviouswith-the structure, a'sdefin'edthat insurance' i'sfprovided fory the contentsofthe sack.VVA i" AVFirst of all, if the exterior canvas is sub- 'jectd tofilame'fit will withstand a great e event if its gtegagrsaumad with 'will ,not neCeSSarly destroyhe .next course ofucanvas or. duck impregnated fabric, as

bags. In any event, fire will scarcely reach the inner rubber containers, C, D.

In case fire destroys the two outer covers or one of them, the two inner bags will still have sutiicient buoyancy to float the bag and its contents when the fire is extinguished.

It follows that there is proof against loss by lire directly, and proof against loss in the event of the bag and contents falling into streams or the sea.

This would seem to give adequate protection covering air mail service for which the bag as illustrated in the drawings, is particularly designed.

The invention, however, may be applied to any receptacle to give the same sort of protection-as described.

It is quite obvious that modifications as to exact structure and conformation and clamping parts may be modified to suit the exigencies of any particular requirement and those shownherein and' describedare merely exein` plary andany'ordinary modifications are to be considered within the terms of the inventiveidea, Ias expressed.'VV l `That we claim' as our invention and vde` sire to secure'by Letters Patent is l.
